PHPCMS快速建站系列之类别调用及类别显示页面

在需要调用类别的地方,比如列表页,首先写循环前面写上一句:

<?php $TYPE = getcache('type_content','commons');?>

这句就是把类别缓存加载进来.

然后在循环里写:

<a href="index.php?m=content&c=type&catid={$catid}&typeid={$r[typeid]}">{$TYPE[$r[typeid]][name]}</a>

这样就可以调用出来类别了.

不过链接暂时无效.因为还没有做好链接文件.后面会更新这个文件的.

类别链接页面:
新增一个 type.html 文件放到 phpcms\templates\default\content\ 下:
该文件代码如下:

{template "content","header"}
<!--main--><?php $typeid = intval($_GET['typeid']);?>
<div class="main">
<div class="col-left">
     <div class="crumbs"><a href="{siteurl($siteid)}">首页</a><span> > </span>{catpos($catid)} 类别：<font color="red">{$TYPE[$typeid][name]}</font> 总共有 {$total} 条记录</div>
        <ul class="list lh24 f14">
{loop $datas $r}
<li><span class="rt">{date('Y-m-d H:i:s',$r[inputtime])}</span>·<a href="{$r[url]}" target="_blank"{title_style($r[style])}>{$r[title]}</a></li>
{if $n%5==0}<li class="bk20 hr"></li>{/if}
{/loop}
        </ul>
        <div id="pages" class="text-c">{$pages}</div>
  </div>
    <div class="col-auto">
        <div class="box">
            <h5 class="title-2">频道总排行</h5>
             {pc:content action="hits" catid="$catid" num="10" order="views DESC"}
            <ul class="content digg">
    {loop $data $r}
     <li><a href="{$r[url]}" target="_blank">{$r[title]}</a></li>
    {/loop}
            </ul>
            {/pc}
        </div>
      
    </div>
</div>
{template "content","footer"}

 

新增一个 type.php 文件到 phpcms\modules\content\下,该文件代码如下:

<?php
defined('IN_PHPCMS') or exit('No permission resources.');
//模型缓存路径
define('CACHE_MODEL_PATH',CACHE_PATH.'caches_model'.DIRECTORY_SEPARATOR.'caches_data'.DIRECTORY_SEPARATOR);
pc_base::load_app_func('util','content');
class type {
private $db;
function __construct() {
  $this->db = pc_base::load_model('content_model');
}
/**
  * 按照模型搜索
  */
public function init() {
  if(!isset($_GET['catid'])) showmessage(L('missing_part_parameters'));
  $catid = intval($_GET['catid']);
  $siteids = getcache('category_content','commons');
  $siteid = $siteids[$catid];
  $this->categorys = getcache('category_content_'.$siteid,'commons');
  if(!isset($this->categorys[$catid])) showmessage(L('missing_part_parameters'));
  if(isset($_GET['info']['catid']) && $_GET['info']['catid']) {
   $catid = intval($_GET['info']['catid']);
  } else {
   $_GET['info']['catid'] = 0;
  }
  if(isset($_GET['typeid']) && trim($_GET['typeid']) != '') {
   $typeid = intval($_GET['typeid']);
  } else {
   showmessage(L('illegal_operation'));
  }
  $TYPE = getcache('type_content','commons');
  $modelid = $this->categorys[$catid]['modelid'];
  $modelid = intval($modelid);
  if(!$modelid) showmessage(L('illegal_parameters'));
  $CATEGORYS = $this->categorys;
  $siteid = $this->categorys[$catid]['siteid'];
  $siteurl = siteurl($siteid);
  $this->db->set_model($modelid);
  $page = $_GET['page'];
  $datas = $infos = array();
  $infos = $this->db->listinfo("`typeid` = '$typeid'",'id DESC',$page,20);//读取整个模型下同类别文章
  //$infos = $this->db->listinfo("`typeid` = '$typeid' AND catid = '$catid'",'id DESC',$page,20);//仅仅读取当前栏目下的同类别文章,如果要启用此模式,请去掉上一行代码并将本行开头的// 两斜杠去掉.
  $total = $this->db->number;
  if($total>0) {
   $pages = $this->db->pages;
   foreach($infos as $_v) {
    if(strpos($_v['url'],'://')===false) $_v['url'] = $siteurl.$_v['url'];
    $datas[] = $_v;
   }
  }
  $SEO = seo($siteid, $catid, $TYPE[$typeid]['name'],$TYPE[$typeid]['description'],$TYPE[$typeid]['name'].'类别');
  include template('content','type');
}
}
?>

上面的链接即可生效.
需要注意的是:
  $infos = $this->db->listinfo("`typeid` = '$typeid'",'id DESC',$page,20);//读取整个模型下同类别文章
  //$infos = $this->db->listinfo("`typeid` = '$typeid' AND catid = '$catid' ",'id DESC',$page,20);//仅仅读取当前栏目下的同类别文章,如果要启用此模式,请去掉上一行代码并将本行开头的// 两斜杠去掉.
